Description

The utility model relates to the field of production of road-building constructions and products from sulfur concrete, used, in particular, for arranging street-road networks, playgrounds and squares, and more specifically, to forms for the manufacture of curbs.

The closest analogue of the claimed utility model is a mold for the manufacture of cast mixtures, for example, sulfur concrete products, consisting of bonded equipment (sides) and a pallet that form a filling cavity for the formed product (patent RU 2052343, B28B 5/06, 01/20/1996 )

The technical solution mentioned above has a low productivity, because it is possible to form only one unit of the product.

The task to which the claimed utility model is directed is to create a mold for the manufacture of cast sulfur-concrete products without the above disadvantages.

The claimed utility model allows to achieve the following technical results:

- improving the physico-mechanical characteristics of the products (molded using the inventive casting mold), in particular, strength, with the exception of cracking during solidification and cooling in the mold, and, as a result, increasing the service life of molded using the claimed mold;

- increasing the productivity of the mold for casting sulfur concrete products due to the fact that the filling cavity is divided into two identical sections.

The problem is solved by the fact that the mold for the manufacture of cast sulfur-concrete products, mainly curbs, consists of longitudinal and transverse sides and a pallet connected to each other, which form a filling cavity for the formed product. The mold is equipped with two partitions which are connected to the pallet and to the longitudinal or transverse sides. In the upper part of the partition are interconnected by a wall and divide the filling cavity into two sections. The transverse sides are detachably connected to the longitudinal sides and in the sides with which the partitions are fastened, longitudinal openings opposite each other are made, paired with the space between the partitions. Said openings together with the partitions, the wall and the part of the pallet located between the partitions form a channel for a cooling agent.

The mold is equipped with a propulsion device, which is made, for example, in the form of at least two wheelsets and means of coupling with said propulsion device.

The presence of a channel for a cooling agent ensures uniform cooling of the formed sulfur-concrete products throughout the volume of the mold during the solidification of the said products. Thus, the occurrence of internal thermal stresses in the volume of the molded product is excluded and, as a result, crack formation is eliminated. The productivity of the technological line in which the claimed form is used is doubled due to the division of the filling cavity into two identical sections.

The essence of the utility model is illustrated by drawings.

Figure 2 shows a side view of the mold for the manufacture of cast sulfur concrete products;

Figure 3 shows a top view of the mold for the manufacture of cast sulfur concrete products;

Figure 4 shows a General view of the mold for the manufacture of cast sulfur concrete products in isometric projection.

Mold elements for the manufacture of cast sulfur-concrete products, in particular, curbs in graphic materials are indicated by the following positions:

1 - wall connecting partitions in the upper part;

2 - partitions;

3 - the first section of the filling cavity;

4 - the second section of the filling cavity;

5 - longitudinal holes in the sides;

6 - transverse side;

7 - longitudinal board;

8 - pallet;

9 - mover of the highway in the form of wheelsets.

The mold for the manufacture of cast sulfur-concrete products consists of transverse 6 and longitudinal 7 sides and a pallet 8. The sides and pallet 8 form a filling cavity for the formed product. The side walls 6 are detachably connected to the longitudinal sides 7. Inside the casting cavity, two partitions 2 are installed separating the casting cavity into the first section 3 and the second section 4. The partition walls 2 are fastened with a pallet 8 and with transverse 6 or longitudinal 7 sides. In the upper part of the partition 2 are interconnected by the wall 1. In the sides with which the partitions 2 are fastened, longitudinal holes 5 are arranged opposite each other 5 and are interfaced with the space between the partitions 2. The holes 5 together with the partitions 2, the wall 1 and the part of the pallet 8 located between the partitions 2 form a channel for a cooling agent.

It is advisable that the mold was equipped with means for carrying out its forced translational movement along the technological zone of the automated molding line by means of a mover of the transport line 9, which is made in the form of at least two wheelsets, as well as means of coupling with the said mover.

A mold is used for the manufacture of cast sulfur concrete products as follows.

The mold is used on an automated technological molding line for the manufacture of sulfur concrete products. The pallets 8 on which the mold is assembled, with the help of a special pusher, at certain intervals corresponding to the longest technological operation, move along the conveyor line. Moreover, the following technological operations are carried out on an automated technological molding line for the production of sulfur concrete products: cleaning, assembly and lubrication of molds, installation of reinforcement and pouring sulfur concrete solution, compaction of the mixture, hardening of sulfur concrete and formwork. At the same time, the installation of reinforcement is not a mandatory technological operation and in some cases may be absent.

Before pouring sulfur-concrete mortar into the mold, fasten the transverse sides 6 and the longitudinal sides 7 of the form together. Then both identical sections 3 and 4 of the casting cavity are filled with hot sulfur-concrete solution having a temperature of 120 ° -140 ° C. In channel 5 for the cooling agent, uniform cooling by a cooler, for example, air, of the formed concrete products throughout the entire volume of the mold during solidification takes place. When sulfur concrete gains the necessary strength, allowing you to start form stripping, i.e. the curing process of the solution will end, the stripping of the formed sulfur concrete product begins, by disconnecting the transverse sides 6 from the longitudinal sides 7.

After stripping, the finished sulfur concrete product is removed from the pallet and transported to the place of storage and storage.

Thus, the claimed technical solution can be widely used in the production of road-building structures and products from sulfur concrete, used, in particular, for arranging street-road networks, playgrounds and squares.
